BACKGROUND OF THE INVENTION Field of the Invention

The present invention relates to an automatic bending apparatus for acopper pipe connector, and more particularly, to an automatic bendingapparatus for a copper pipe connector that is capable of curvedlybending the copper pipe connector through a single operation.

Background of the Related Art

A pipe is mainly used to convey a fluid such as gas or liquid, powder,or the like in living or industrial facilities. The pipe is bent tovarious angles when its installation direction is changed or itsinstallation area is limited.

Generally, a pipe bending apparatus is configured to allow one end of apipe to be fixed to a curvature starting point of a rotating mold havinga desired curvature and to then allow the pipe to come into closecontact with an outer peripheral surface of the rotational mold by meansof a roller in such a manner as to be moved along the outer peripheralsurface of the rotational mold and to be thus bent to the same curvatureas the rotating mold.

According to the conventional pipe bending apparatus, however, a section(diameter) of the pipe may be deformed (distorted) in the process wherethe pipe has plastic deformation along the curvature of the outerperipheral surface of the rotating mold, and as a result, thedeformation on the section of the pipe causes a resistance of a fluidflowing along the pipe.

A roller pipe bending apparatus is disclosed in Korean Patent No.10-0683170, and an automatic bending apparatus is disclosed in KoreanPatent No. 10-0583206.

Moreover, a connection plate 311 is located on the rear ends of theseating stands 310 to connect the seating stands 310 thereto, and also,the cylinder C2 is connected to the connection plate 311.

Furthermore, seating grooves 312 are formed on one side of the seatingstands 310 so that the copper pipe connector 10 can be stably seatedwithout shaking or or falling.

The position adjusting rods 320 are located on both sides of top of thebody 100 in such a manner as to come into contact with both ends of thecopper pipe connector 10 seated onto the seating stands 310 by means oflinear motions to thus allow the copper pipe connector 10 to be adjustedto the accurate bending position.

The first bending part 400 is located on top of the body 100 to allowthe copper pipe connector 10 seated onto the seating stands 310 of thebending position adjusting part 300 to be bent to a given curved shape.

As shown in FIGS. 1 and 6, the first bending part 400 includes the firstbending body 410, a first support member 420, and a first bending member430.

The first bending body 410 is located on top of the body 100 in such amanner as to be connected to the seating stands 310 of the bendingposition adjusting part 300.

The first support member 420 is located on top of a front surface of thefirst bending body 410 in such a manner as to come into close contactwith half of the copper pipe connector 10 seated onto the seating stands310.

Further, the first support member 420 has a first bending groove 421formed rounded on an outer side of the front surface thereof in such amanner as to allow one side of the copper pipe connector 10 to becurvedly bent in the state of coming into close contact with the copperpipe connector 10, while the copper pipe connector 10 is being bent bymeans of an operation of the first bending member 430.

The first bending member 430 is connected to the front surface of thefirst bending body 410 by means of a hinge h in such a manner as torotate around the hinge h to thus allow one side of the copper pipeconnector 10 to be curvedly bent.

Further, a cylinder C3 is connected to the first bending member 430 toallow the first bending member 430 to rotate around the hinge h.

The second bending part 500 is located on top of the body 100 to facethe first bending part 400 and serves to bend the copper pipe connector10, together with the first bending part 400.

In the state where the first bending part 400 and the second bendingpart 500 face each other, in detail, they curvedly bend both sides ofthe copper pipe connector 10 in different directions from each other.

As shown in FIGS. 1 and 7, the second bending part 500 includes a secondbending body 510, a second support member 520, and a second bendingmember 530.

The second bending body 510 is located movably on top of the body 100along rails (R1 and R2) in such a manner as to face the first bendingmember 410.

Further, the second bending body 510 is connected to a cylinder C4 andis moved along the rails (R1 and R2) by means of an operation of thecylinder C4, so that it can come into contact with the first bendingmember 410.

The rails (R1 and R2) are located on the underside of the second bendingbody 510 to move the second bending body 510 through the operation ofthe cylinder C4.

The second support member 520 is located on top of the front surface ofthe second bending body 510 in such a manner as to come into closecontact with half of the copper pipe connector 10 seated onto theseating stands 310.

Further, the second support member 520 has a second bending groove 521formed rounded on an outer side of the front surface thereof in such amanner as to allow the other side of the copper pipe connector 10 to becurvedly bent in the state of coming into close contact with the copperpipe connector 10, while the copper pipe connector 10 is being bent bymeans of an operation of the second bending member 530.

In detail, the copper pipe connector 10 comes into close contact withthe first bending groove 421 and the second bending groove 521, and whenit is bent, accordingly, it does not twist. While the first bendingmember 430 and the second bending member 530 are operating, further, oneside of the copper pipe connector 10 can be bent curvedly, without anywrinkle, by means of the rounded surfaces of the outer sides of thefirst bending groove 421 and the second bending groove 521.

The second bending member 530 is connected to the front surface of thesecond bending body 510 by means of a hinge h in such a manner as torotate around the hinge h to allow the other side of the copper pipeconnector 10 to be curvedly bent.

Further, a cylinder C5 is connected to the second bending member 530 toallow the second bending member 530 to rotate around the hinge h.

Furthermore, angle adjusting stands 130 are located on top of the body100, that is, on side portions of the first bending part 400 and thesecond bending part 500, to adjust rotation angles of the first bendingmember 430 and the second bending member 530 according to bendingcurvature angles of the copper pipe connector 10.

The angle adjusting stands 130 can rotate by means of bolt tightening toadjust the rotation angles of the first bending member 430 and thesecond bending member 530.

The controller 600 is located above the side surface of the body 100 insuch a manner as to be connected electrically to the respective parts tocontrol their operations.

Under the above-mentioned configuration, now, an explanation on anoperating state of the automatic bending apparatus for the copper pipeconnector according to the present invention will be given.

The copper pipe connector 10 to be bent is supplied to an interior ofthe supply container 210, and next, it is lifted onto the concavegrooves 221 of the ascending and descending bars 220. If so, theascending and descending bars (220 and 220 a) are moved up until theyare on top of the supply container 210 by means of the operation of thecylinder C1.

If the ascending and descending bars (220 and 220 a) are moved up, theguide robot 230 holds the copper pipe connector 10 placed on the concavegrooves 221 to move the copper pipe connector 10 above the dischargehole 120 of the body 100, and if so, the seating stands 310 are movedforward toward the discharge hole 120 by means of the operation of thecylinder C2, so that the copper pipe connector 10 is released from theguide robot 230 and is thus placed on the seating stands 310 (See FIG.8).

In this case, the copper pipe connector 10 is placed on the seatinggrooves 312 formed on the seating stands 310, so that it is stablyseated thereonto, without any movement, thereby enhancing a bendingefficiency.

If the copper pipe connector 10 is placed on the seating stands 310,further, the second bending body 510 is moved along the rails (R1 andR2) by means of the cylinder C4 to push the copper pipe connector 10, sothat the copper pipe connector comes into close contact with a spacebetween the first support member 420 and the second support member 520.

In this case, the copper pipe connector 10 comes into close contact withthe first bending groove 421 of the first support member 420 and thesecond bending groove 521 of the second support member 520, so that itcan be stably bent, without any movement.

If the copper pipe connector 10 comes into close contact with the firstbending groove 421 and the second bending groove 521, further, theposition adjusting rods 320 located on both sides of the body 100 arelinearly moved to come into contact with both side ends of the copperpipe connector 10, so that the bending positions of the copper pipeconnector 10 can be accurately adjusted (See FIG. 9).

If the bending positions of the copper pipe connector 10 are adjustedthrough the bending position adjusting part 300, the first bendingmember 430 and the second bending member 530 rotate around the hinges hby means of the operations of the cylinders C5 to allow both sideperipheries of the copper pipe connector 10 coming into close contactwith the first support member 420 and the second support member 520 tobe bent curvedly in different directions from each other (See FIG. 10).

If the copper pipe connector 10 is bent by means of the operations ofthe first bending member 430 and the second bending member 530, further,the second bending body 510 is moved along the rails (R1 and R2) bymeans of the operation of the cylinder C4 to allow the first supportmember 420 and the second support member 520 to be separated from eachother, and accordingly, the bent copper pipe connector 10 can bedischarged to the discharge hole 120 (See FIG. 11).

Like this, the plurality of copper pipe connectors 10 are automaticallysupplied one by one to the seating stands 310 of the bending positionadjusting part 300 from the supply part 200, and the seated copper pipeconnector 10 comes into close contact with the first bending groove 421of the first bending member 420 and the second bending groove 521 of thesecond bending member 520. Next, the bending positions of the copperpipe connector 10 are accurately adjusted through the position adjustingrods 320, and through the operations of the first bending member 430 andthe second bending member 530, the copper pipe connector 10 is bentcurvedly and discharged. The bending and discharging processes of thecopper pipe connectors can be continuously carried out, therebymaximizing the efficiency of work.

As described above, the automatic bending apparatus for the copper pipeconnector according to the present invention supplies the copper pipeconnector to the bending position adjusting part from the supply part,accurately adjusts the bending positions of the copper pipe connector,and automatically bends the copper pipe connector through the singleoperation of the first being part and the second bending part in such amanner as to allow both ends of the copper pipe connector to be curvedin different directions, thereby maximizing a quality of a product andstability and conveniences in work.
